In long run there is a strong trend to gain money investing in natural diamonds and a strong trend to lose money purchasing lab-grown diamonds.

Second difference are physical and chemical distinctive features

Natural diamonds

Natural diamonds were formed for millions of years by the chemical and physical reactions deep inside the Earth. Thence, the combinations of nitrogen in the lattice of natural diamond could not been created by man.

The mechanical properties of natural diamonds are attractive for producers of diamond instruments (instruments made solely from synthetic diamonds have shorter lifespan)

Synthetic lab-grown diamonds

Synthetic lab-grown diamonds available on the market are created in a few days or a few weeks in the laboratory. Such stones have different picture of growth lines in comparison to natural diamonds.

Chemical catalysts are used to speed the growth process of synthetic diamonds. So by the means of laboratory equipment you can find chemical elements like Fe (iron), Ni (nickel), Co (Cobalt) etc. in such chemical state that is inherent for lab-grown diamonds and extrinsical for natural diamonds.

By the use of expensive laboratory equipment (for example optical) every synthetic diamond could be distinctively defined with 100% of confidence level as synthetic/lab-grown. The man still is not able to properly re-construct natural diamond. But even experienced gemologist with standard gemological loupe and some simple equipment (like simple $2000 ultraviolet gem tester) can’t make a reliable assessment of natural diamond authenticity – it will be only a subjective assessment of human who has a limited experience.

Thousands of specialists take part to bring natural diamonds from Earth to market. Natural diamonds have a million-year history.

Each natural diamond has unique characteristics – it’s hard to find similar and impossible to find a copy of natural diamond.

Synthetic lab-grown diamonds

Synthetic diamonds are grown relatively easy and quick at the labs or factories (from days to weeks).

There is a market of equipment for HPHT- or CVD-growth of diamonds. So any enthusiast could try to grow lab-created diamonds with low investment ($9 mln investments for production volumes of 100 000 carat per year);

In order to grow synthetic diamonds a few specialists are needed;

Synthetic diamond are grown from a diamond seed (HPHT-technology) or a diamond plate (CVD-technology). Synthetic diamond copies could be made by the means of HPHT or CVD-technology.

All collaborative effort of Earth and human results in a strong emotional value and energy of a true natural diamond. In comparison, synthetic lab-grown diamond is of low emotional value.

The difference between natural diamonds and man-treated/enhanced diamonds:

If the natural diamond is man-treated, such stone could been identified by the means of laboratory equipment with 100% level of confidence as man-treated diamond.

If you have purchased a diamond and discovered afterwards that it was man-treated, such diamond has lost a significant part of its price because it was made from the natural diamond that was much cheaper and from now it will be sold not as a natural diamond but as a man-treated.

If your customer will discover that he has purchased undisclosed enhanced diamond from your shop, there will be a public and financial strike for your business reputation.

Avoid undisclosed man-treated diamonds because it could be dangerous for your reputation and finance

ALROSA Diamond Inspector is a mini-laboratory for complex optical test of polished natural diamonds authenticity to be used by jewelry shops, pawn shops and gemologists

ALROSA Diamond Inspector is the only portable diamond detector on the market designed to identify natural origin of polished diamonds using three analytical methods.

Maximum result reliability

Result quality was proved by tests on various collections of natural, synthetic, enhanced diamonds and simulants.

A great deal of expert experience, scientific knowledge and effort were put into the device. ALROSA DIAMOND INSPECTOR was developed jointly by the world’s largest by volumes natural diamond mining company ALROSA (PJSC) and a scientific institute TISNCM. TISNCM specializes in R&D of superhard and novel carbon materials for technical application including HPHT- and CVD-diamond synthesis.

Stones could have various cutting shapes**** and carat weight ranging from 0.03 to 10 carats

Test stones in jewelry

Test stones in rings, earrings and other types of jewelry*****

Convenient holders are included in the kit

Beneficial price/quality ratio

ALROSA Diamond Inspector price is substantially lower than that of a set of lab equipment using the same three optical methods.

Patented innovative solution makes price benefit.

Intelligent and user friendly

Less than a minute per test – the duration of the analysis could vary depending on the stone.

Criterions and algorithms applied were developed by the means of scientific expert knowledge and machine learning (neural networks, fuzzy logic.);

With the help of ALROSA Diamond Inspector and no expert knowledge of your own you can check if your diamond is real, natural and untreated.

The result displayed by ALROSA DIAMOND INSPECTOR aggregates automatically the results of all 3 optical methods and gives you a clear unified result. Whereas if you use a set of 3 separate analytical appliances you should make the decision by yourself relying on your subjective opinion and discrepant results generated by 3 separate appliances.

Portable and autonomous

The overall dimensions of ALROSA Diamond Inspector are:

You may choose ALROSA Diamond Inspector with metal or plastic frame. The net weight of the device is:

3.1 kg with metal frame

1.8 kg with plastic frame

ALROSA Diamond Inspector doesn’t need the Internet connection or a computer.
It can be powered by power adapter or power bank.

Functional and Ergonomic

The device can be used in:

jewelry shops,

pawn shops,

online jewelry stores,

offices,

gemological laboratories,

on business trips,

at business transactions.

Sustainable and safe

ALROSA Diamond Inspector is reliable and safe to use.

It doesn’t need any special care.

Manufacturer’s warranty

A manufacturer warranty for 1 year is provided for each device.

You may purchase additional warranty before your current warranty will expire.

* — near-colorless relates only to yellow color D-K and doesn’t relate to blue, green, pink and other low-intensive colors;
** — in very rare cases natural diamonds could have been slightly enhanced by nature (not by man). There is no laboratory equipment that will define with 100% level of confidence that such rare stones were enhanced by nature. So one enhanced stone is traded like enhanced stone no matter how it was treated – by man or by nature;
***- some rare natural diamonds could have the same optical properties as CVD, HPHT-synthetic diamonds. A set of expensive lab-equipment could define the authenticity of diamond with 100% level of confidence.
**** — The device is intended only for working with diamonds and imitations that have a diamond cut with a table/flat face of different form that has a round flat area with diameter 1,5 mm or larger (approximately 3,2 mm2 or larger).
***** — metal parts of jewelry shouldn’t interfere to lean diamond’s flat area to the inspection slot back to back.
